Kaplan-Meier curves calculated for all patients (n=412) showing (A) locoregional control (LRC), (B) ultimate LRC, (C) freedom from distant disease (FDD), (D) relapse-free survival (RFS), (E) disease-specific survival (DSS), and (F) overall survival (OS) in patients who underwent larynx preservation with induction and/or concurrent chemoradiotherapy (LP-CRT) versus larynx preservation with definitive radiotherapy alone (LP-RT) versus total laryngectomy and post-operative radiotherapy (TL-PORT). Shaded colors represent 95% confidence intervals, short vertical lines represent censored data, and asterisk indicates significant log-rank p values.
